Which of the following properties characterize ionic crystals? (Choose all that apply.)
Low melting point
High boiling point
Conductors of electricity and heat in solid state
Has lattice structure to maximize the attractive forces between positive and negative ions.
Due to the strong electrostatic forces between the ions, ionic crystals have high melting point and high boiling point. They are conductors of electricity and heat only if they are in aqueous states. Ionic solid forms crystal lattices consisting of infinite arrays of positive and negative ions in which the attractive forces between ions of opposite charge are maximized, while the repulsive forces between ions of like charge are minimized.
